EKI-1511 Datasheet (01.17.25) — Specifications, 'Ethernet Communications', rows 'Speed' and 'Compatibility'
home_assistant_modbus_tcp_suitable False
home_assistant_suitability_basis NOT suitable as a Modbus TCP gateway. The datasheet lists the operation modes as COM port redirection, TCP/UDP server, TCP/UDP client and pair connection only; a NONE-forcing read found no occurrence of 'Modbus' anywhere on the sheet. That is a transparent TCP-to-serial tunnel, not Modbus RTU-to-Modbus TCP frame conversion.
max_hosts_per_serial_port 5 hosts
EKI-1511 Datasheet (01.17.25) — Features list, bullet 'Maximum of five hosts can access one serial port'
max_hosts_tcp_client_mode 16 hosts
EKI-1511 Datasheet (01.17.25) — Features list, bullet 'Maximum of 16 hosts accessed in TCP client mode'
modbus_support not documented - the word Modbus does not appear on the EKI-1511 datasheet; documented behaviour is transparent serial transport only
EKI-1511 Datasheet (01.17.25) — whole datasheet; NONE-forcing read returned NONE
network_protocols ICMP, IP, TCP, UDP, BOOTP, DHCP, Auto IP, SNMP, HTTP, DNS, SMTP, ARP, NTP
EKI-1511 Datasheet (01.17.25) — Specifications, 'Software', row 'Protocols'
